Input control system for computer keyboard

Abstract

The invention discloses an input control system for a computer keyboard. The system comprises: a remote control input terminal used for inputting a key character, encoding the key character into a remote control signal and sending the remote control signal; a keyboard body comprising a keyboard array and a control mechanism, wherein the control mechanism comprises a remote control switch, a receiving circuit, a decoding circuit, a signal processing circuit, a main control circuit and an output circuit; the remote control switch used for a working state; the receiving circuit used for receiving the remote control signal; the decoding circuit used for decoding the received remote control signal to obtain a digital signal; the signal processing circuit used for performing filtration processing on the digital signal; the main control circuit used for analyzing the digital signal to obtain the key character and generating a character instruction according to the key character; and the output circuit used for executing the character instruction to output the character. According to the system, a character input mode of the computer keyboard is added, so that the computer keyboard is more flexible and efficient to use.

Description

technical field [0001] The invention relates to an input control system for computer keyboards, belonging to the technical field of computer keyboards. Background technique [0002] At present, with the wide application of computer networks, computer keyboards are widely used as input devices. A computer usually includes a host and a keyboard, and the keyboard is used as an input device for the host. A calculator operation circuit has been integrated in the existing keyboard to realize the digital calculation function; the keyboard is usually provided with a switch button, and the user can start the digital calculation function by pressing the switch button, that is, the user needs to manually open the keyboard. Digital calculation function. [0003] The early keyboards were almost all mechanical keyboards, to be precise, mechanical contact keyboards, which used electrical contact contacts as joint signs, and mechanical metal springs as elastic mechanisms. This kind of ke...
